Abstract: PURPOSE:To carry out the daily check of a lifting and lowering device only for the stationary side thereof, and easily and safely carry out a checking work by applying the constitution where the lifting and lowering of a ship with a travel carriage and the motion of the carriage can be all actuated with a fixed drive device. CONSTITUTION:Travel carriages 1 and 1 caused to travel via wheels 17 to 19 on two rails 20 laid in parallel at such a distance as allowing the entry of a ship 23 are installed. Each carriage 1 is constituted of a travel base 27, a vertically extended post or the like, and a lifting beam 25 is so supported on the post as to be capable of freely ascending and descending. The carriage 1 is caused to travel via the motion of a travel chain on the turning of a drive sprocket in a travel drive device laid at the shore side end of the rails 20. The lifting beam 25 is also caused to ascend and descend via a wire on the turning of the winding drum of a lifting and lowering drive device similarly laid at the shore side end of the rails 20. In this case, the ship 23 is elevated or lowered with a sling 24 suspended from the lifting beam 25.

Abstract: PURPOSE:To enable the stable manufacture with good reproductivity of MESFET having food Schottky properties and FET properties by a method wherein the gate pattern having vertical walls is connected into an inverted shape as a gate opening on the coating film and heat treatment for recovering the crystal properties is performed while retaining the gate with the vertical walls thereby filling the gate opening with the gate metal again. CONSTITUTION:An N type operation layer 5 is formed on the high-resistance GaAs substrate 4 and the mask 22 for covering the gate pattern 21 and the periphery of the FET is formed. Then the Si ions are implanted to form a high- concentration impurity layer 6. Subsequently, the substrate is covered with a plasma nitride film 23 and is subjected to the heat treatment in hydrogen to recover the crystal properties of the operation layer 5 and the high-concentration conductive layer 6. Next, a photoresist film 24 is spread and dried to be levelled thinly. Then, the gate pattern 21 is exposed and the photoresist film 24 and the oxide film 21 are removed to form the opening 25. Next, Al is vapor-deposited over the whole surface to form the Al gate electrode 1. On the conductive layer 6, AuGe-Pt is vapor-deposited followed by heat treatment to diffuse AuGe into the conductive layer 6 thereby forming the ohmic electrodes 2 and 3 of the source and drain.

Title: Negative image forming method
Inventor: SAKURAI KIYOMI
IPC: G03F1/00
Filed: 1981-08-07
Abstract: PURPOSE:To form a negative image without using a photosensitive material. CONSTITUTION:A positive image 2 is formed on a transparent base 1 using a transparent nonadhesive material, such as a silicone resin or fluoroplastics by printing or the like, and a light-shading ink or the like is coated on the whole imaging surface.

Title: Quick charging circuit for telephone set power source
Inventor: MASHIO TAKAYUKI
IPC: H04M1/31
Filed: 1986-06-02
Abstract: PURPOSE:To shorten the nonoperation time of a telephone set after its off-hook operation by turning on a transistor(TR) in response to the off-hook operation of the telephone set, charging the power source in the telephone set quickly with a voltage generated across a diode, and turning off the TR when the source voltage in the telephone set reaches a constant voltage. CONSTITUTION:When the telephone set enters the off-hook operation, hook switches HS1 and HS2 are closed. At the point of time of the off-hook operation, the source terminal VDD in the telephone set is 0 V and while a TR Q3 is off, TRs Q2 and Q1 are on; and a current from a trunk line flows in the order of an intraoffice connection terminal L1, a diode bridge REC, the Q1, a D1, the REC, and an L2 to charge a capacitor C1, thereby obtaining a source voltage VDD in the telephone set. When the voltage VDD reses, the TR Q3 turns on while delayed by the time when the TR Q3 turns on, the TRs Q2 and Q1 turn off, so that this circuit finishes operating. Consequently, the nonoperation time of the telephone set after its off-hook operation is shortened.

Abstract: PURPOSE:To reduce errors caused by reflecting conditions without moving the measuring device or a measuring object by interposing a collimator lens between a light source and the measuring object, obtaining a plurality of received rays while the aforesaid lens is being made to deviate, and thereby outputting the received rays. CONSTITUTION:A deviation mechanism is operated by control signals from a deviation signal generator 11, a collimator lens 121 is thereby operated in a range of on or about 50mum, a projected light beam 2 is thereby swung in a very small distance in the right angle direction against the surface of paper, and a light spot 4 over a measuring object 3 is scanned in the lateral direction in a range of on or about 1mm. The output of reflected light is then detected during scanning by a light detector 7 so as to be operated 9, and its result is corrected by a correction circuit 10 so as to be inputted into an averaging circuit 12. In the circuit 12, a plurality of deviation outputs 100 which can be obtained by the one time movement (scanning) of the light spot 4 in the lateral direction, is processed by means of addition averaging (space averaging method), and the result is outputted thereafter. By this constitution, the effect of irregularities over the light spot 4 can be eliminated by a small size, simple and inexpensive mechanism, and measurement error caused by reflecting conditions are thereby lessened.
